Danny Phantom (as Danny Phenton) appears as a playable character. After several nicktoons end up in the wrong dimension Jimmy Neutron sends him and others to take a picture of them to send them back. Later it is discovered that Invader Zim was the cause of the mix up.

Danny is recruited from his homeworld by Jimmy Neutron when several villains start to work together to drain the worlds out of energy. The heroes travel through Amity Park (Danny's homeworld), Bikini Bottom, and Fairy World, defeating all the villains along the way. They later learn of The Evil Syndicate's master plan: to feed the stolen energy to their Doomsday Device, so they can destroy all worlds in a matter of seconds. In Retroville, the villains team up to attemt to attack the heroes all at once. Danny however, defeats Vlad Plasmius, and the other heroes defeat their respective foes as well. They also stop the Doomsday Device, saving the Multiverse.
